Abstract (en)
A boiler (1) comprising at least: a furnace (2), in whose lower part the combustion used as the primary source of thermal energy of the boiler is configured to take place; devices (6) for supplying fuel into the furnace; devices (3, 7, 8, 26) for supplying combustion air into the furnace; one or more flue gas ducts (11); at least one chamber (17) accommodating at least one steam superheater (15) for recovering thermal energy. Said chamber is configured to allow a direct line of sight (16) between said superheater and said primary source, to enable the reception of thermal energy by means of thermal radiation. Said chamber is further configured to prevent the entry of said flue gases (19) to said superheater either totally or almost totally, to avoid the reception of thermal energy by convection.
